Inventor: HERMS JAMES K
IPC: A61F2/00

Abstract: A blood clot filtration device, for implantation percutaneously, for preventing movement of blood clots within a blood vessel. The device has a head (14) and a plurality of legs (12) extending therefrom. The legs (12) include a first linear leg portion (13) of predetermined length emanating distally from the head (14) generally parallel to the axis of the device; a second multi-angled leg portion of relatively greater length extending generally outwardly from the distal end of the first linear leg portion at an acute angle to the axis, to form, with other second leg portions, a conical aspect, the second leg portion having a series of discrete linear segments (38) arrayed generally tangent to a cone defined by the second leg portions of the set of legs; and a hook portion (22) at the distal end of each the leg extending outwardly, away from the axis in a manner for engaging the blood vessel to fix the position of the device therewithin. The configuration of the legs (12), including the first linear portion (13), and the use of a high strength titanium alloy for the head (14), formed by fusing, and legs produces a filter which is able to tolerate severe compression for introduction percutaneously through a small sheath without yeilding. Preferably a central wire segment (24) is disposed axially, with the first linear leg portions (13) of the filter disposed closely thereabout.

Abstract: An MIS power transistor is to be capable of being operated in the case of an avalanche without being destroyed using a current which is as high as possible above the nominal current. This is achieved in that the cell field (Z) is surrounded by cells (14) of a different cell type whose source zones (3) have smaller lateral dimensions, at least in the direction towards the edge of the cell field, than the source zones (3) of the internal cells (12) of the cell field. In this way, the avalanche current which flows mostly at the edge of the cell field can be increased without the parasitic bipolar transistor being switched on and the transistor being destroyed. <IMAGE>

Filed: 1988-06-28
Abstract: A slalom post (1) is described comprising at least one eccentrically pivoted disc-like anchor element (5, 8) normally positioned substantially within the cross-sectional area of the lower end of the post. By simply twisting the slalom post (1) around its vertical longitudinal axis (4), the anchoring element (5, 8) is brought from its normal ineffective position into its effective anchoring position by rotation around a vertical axis offset and parallel to the vertical longitudinal axis of the slalom post. If desired, a roughened peripheral edge of the disc may be provided for engagement with the snow or ice into which the lower end of the post is placed so that the rotation of the post will rotate the disc-like anchoring element relative thereto to move it into its effective anchoring position. A stop or guide means may be attached to the post or the extension thereof containing the anchoring element in order to limit the orthogonal projection of the anchoring means in both its ineffective and most effective positions. Furthermore, sleeves may be provided over the lower end of the post for indicating whether the post is to be rotated clockwise or counterclockwise and for lining the hole into which the end of the slalom post is to be inserted.

Abstract: In counterbalancing masses which can be produced from concrete, one edge of a reinforcing part projects annularly as a connecting element from a basic body made of concrete. The counterbalancing mass can be connected to a lye container by means of this edge and an outer ring. The use of an outer ring increases the outlay involved in the fastening of counterbalancing masses. So that counterbalancing masses can be connected simply and in an at least partially automatable way, connecting elements (7, 15, 15') can be connected to the reinforcing part (5, 5') and each have for a screw connection a passage orifice (9, 19, 19') and, adjacent to this, a region located outside the concrete. The counterbalancing mass is suitable for use in washing machines, spin-dryers or the like. <IMAGE>

Abstract: A planar, p-n junction device has electrical contact made to the active region, the capping layer (4) having been selectively removed through a mask (5, 6). The selective removal of the capping layer may be performed prior to a diffusion step in which the junction is formed, or the dopant may be diffused through the capping layer (4) and the selective removal performed subsequently. In the latter instance the capping layer (4) is preferably etched through a second mask (8,9) having a smaller window (9) in register with the window (6) in the mask layer (5) which is used for the diffusion stage. 
     The device finds particular application as a photodiode detector in optical communications.

Abstract: In a process for separating aminoacids from a mixture containing them using non-exchange resins, the mixture is passed successively over several columns arranged in series and filled respectively with an absorptive material, a first ion-exchange resin, and a second resin which exchanges oppositely-charged ions. Preferably the mixture is passed at least once succesively over the same two columns of anion and cation-exchange resins. Each column can be previously oxidized by an oxidizing agent. This process permits a high degree of separation of a complex mixture of amino acids derived, in particular, from the hydrolysis of proteins without the addition of external agents.

Abstract: The invention relates to a method for filling bottles or similar vessels with liquid, and to a filling head used in this method. The filling head has a liquid valve and a dispensing orifice, via which the liquid flows to the vessel to be filled, via its vessel orifice, in the filling phase with the liquid valve open. In a rinsing phase prior to the filling phase, the inside of the particular vessel has a rinsing gas applied to it via a tubular piece penetrating into this inside through the vessel orifice, which rinsing gas emerges at an orifice of a gas duct provided at the lower end of the tubular piece. The outlet orifice is here designed as an annular orifice surrounding the vertical filling head axis concentrically. Residual amounts of air remaining in the vessel after the rinsing are conclusively reduced, in spite of the shortened rinsing time, by introducing the rinsing gas via this annular orifice into the inside of the vessel.
